Simplest Two-Point Grounding:
Two 2.5m galvanized angle steels, spaced strictly 5m apart, are connected laterally by 40×4 flat steel bars. One end of the flat steel is led to the flange base of the streetlight pole for welding grounding.
Triangular Three-Point Grounding:
Three angle steels are arranged in an equilateral triangle, with each adjacent pair spaced 5m apart, forming a closed grounding loop. This results in more stable grounding resistance and stronger lightning protection.
Multi-Pole Series Grounding Along the Road:
Each streetlight pole's grounding branch is connected to a horizontally running flat grounding steel strip along the road's longitudinal direction. A set of vertical grounding angle steels is installed every 5m along the flat steel strip, forming a complete grounding network.
